Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a dedicated apparatus with integrated illumination and camera is used to reduce installation burden, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent combines the illumination apparatus and camera into a single integrated inspection apparatus. The illumination section and imaging section are merged into one device, allowing the user to operate a single unified system rather than separately installing and coordinating multiple components, thereby reducing installation burden while maintaining functional integrity
2Manufacturing precision
If multiple control parameters are adjusted to generate accurate inspection images, then manufacturing precision is improved, but ease of operation deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the inspection image is immediately displayed on the display unit after being generated from luminance images by the inspection image generating unit. This allows the user to see the result of parameter adjustments in real-time and intuitively verify whether the inspection image is correct, enabling iterative optimization of control parameters with direct visual feedback
3Device complexity
If only the inspection image is displayed to allow parameter adjustment, then device complexity is reduced, but ease of operation deteriorates due to difficulty in intuitively verifying image correctness
Solution Approach 1:
The patent introduces the display unit as an intermediary between the inspection image generating unit and the user. This display unit serves as a mediator that presents the generated inspection image to the user in a visually accessible manner, enabling the user to intuitively assess image quality and make informed parameter adjustments without directly interacting with complex processing systems

AI summary
To facilitate setting of a parameter at the time of generating an inspection image from an image acquired by using a photometric stereo principle. A photometric processing part generates an inspection image based on a plurality of luminance images acquired by a camera. A display control part and a display part switch and display the luminance image and the inspection image, or simultaneously display these images. An inspection tool setting part adjusts a control parameter of the camera and a control parameter of an illumination apparatus. Further, when the control parameter is adjusted, the display control part updates the image being displayed on the display part to an image where the control parameter after the change has been reflected.
